Re: [RFC PATCH 00/11] drm/i915: Expose OA metrics via perf PMU

[Peter Zijlstra]

So I've not yet went through the entire series; but I'm wondering if its
at all possible to re-use some of this work:

lkml.kernel.org/r/1428453299-19121-1-git-send-email-sukadev@xxxxxxxxxxxxxxxxxx

That's for a Power8 HV call that can basically return an array of
values; which on a superficial level sounds a bit like what this GPU
hardware does.

Let me read more of this..
